Filter does not go back to page 1

I have a paged grid with filtering. If I page to say page 9, then select a filter, which filters down to 1 page, the "start" value I get on the server is still where it was while at page 9. So for example, it will say page 9 of 1 - and no data displayed. Very confusing for the users.
